OP, keep I'm mind that the M3 has a V8 under the hood, so different systems will bring out a different characteristic of the engine. The Gintani will bring out the deep sound of the V8, whereas the Meisterschaft will bring out the higher pitch of the V8, but both will be unmistakably V8 sounding in character. It really just depends on which character you prefer.

I was thinking about it but decided not too. I think I'm going to stop at the axle back. The car really does have enough power for me and it's as loud as I would go. Anything louder would be too much for me as daily driver. I think I may do a Dinan pulley before the summer's over.

That gives you the flexibility of when you want it to be loud...Higher RPMs it does get very high pitched and loud. I have the catless but resonated x-pipe. This will require a tune.
After warm-up you can't even tell if the car has an x-pipe at idle.

I am looking into paring this up with a meisterschaft but not sure which one yet.

Please! Get over it! The OP asked about the sound, not the history of the exhausts. Who cares what happened years ago, the new exhaust is completely different design than the Eisenmann. Move on!

I have a Gintani product.. the quality is amazing!!
I have also seen the meisterschaft gt on my friends car and trust me they make great products. I wouldn't look into the past if sound and quality is your concern, and personally i think it (GT) sounds better than the Eise.

Gintani sounds too much like a Chevy small block V8 on steroids. It's a little thick sounding to me. The Meisterschaft on the other hand sounds a little more exotic, more refined. That's just my opinion, but I'm sure the fanboys will chime in and flame me for my comment. Either way, I doubt you'll ever feel the extra 10hp that an axle back will give you. Buy it for sound, not power.

I agree, these 2 models sounded too American to be associated with an M3. Seriously, after having read and re-read all the threads and posts on the exhaust, after having heard it myself a dozen different exhausts and if the performance gain is not your priority, the best sound I've heard up 'here (that better meets the original sound but more powerful) is the Remus Race. The system is poorly known (very poor representation in U.S. and Canada) but it is worth to be considered because it is more in harmony with the concept of an M3: just loud enough at low revs, not too drone at mid speed and a sound mad enough to acute high revs. Very surprising from a system less known and the quality / price seems unbeatable.

Remus Race is pretty well known on this site and enough people have it on their M's. Way too much drone for me.
